' To all whom it'r'nay COW/06.7.1725; a

.B e it known that I, WA TER G. WUIOHET, a citizen of the. UnitedStates, residing at the following is a s ecification.

My invention re ates to improvements 'useful Improvements C'olers,'.ofwhich in 7 common supply andjdischar'ge chamber connectedtherewith. Theobject of my invention istoprovide an improved cooler ofjthe type havinga storage fieservoir therein jsuchthat when the dischar eis open only alimited uantity of the.

Dayton, in the county of Montgomeryand State of Ohio, haveinventedcertain new and coolers and more especially to that. type ofcooler employing an innerreservoir' with a With this andother. objectsit View my inf In the accompanying drawings, Figure 1 is reduced inlet,andFig. 6-

The float may.- be readily removed byunscrewing andtaking ofiithe outer nut, 6 l

c represents a filterofthepressure type, employing the Pasteur system,having a liquid supply inlet, 0', and an outlet, 0 havaconnectionthrough-the casing, a, to the in e't valvechamber, if, said connectioncom-.- prisin pipe fittings'having a cutoff valve, c ,'an a reducer, c;the pipe fittin 0 within the cooling chamber being prefera lycurvedas-shown to present more surface to cool the liquid it carries. Adischarge pipe, 0, likewise curved for the urpose stated, leads from.the chamber, ll and is connected through the caSi g,,.a, with a dischare cook or faucet, a. The said reducer, c, is ocated without thecooling'chamber and consists of. a bodfi having an inlet, a, and outlet0, at rig tangles to each other, with a hollow lug, 0 screw threadedinto saidoutlet, aving a reduced opening, a, leading from said inlet tosaid outlet, said plug-havinga solid extension, 0", with a slot, 0 inits head suitable to receive a screw-driver to,-screw said plugin place.I further provide said body with an o ening through which said] plug canbe read y put in place and removed 35 at pleasure for, cleaning, saidopening being. closed by a screw-threaded cap, 0. An. 5 overflow ipe, api'ojectsl upwardlyin the cooling o amber to a sufficient height tomaintain a quantityof'liquid about a lar e portion of the reservoiraswell asabout t e mlet anddischarge pipes in said chamber.

Itwillbe seen t e liquid supply is conducted through the reducer inlimited quanti-ties into .thereservoir until it reaches a 'heightin saidreservoir suflicientfor the floattoelose the, inlet valve. The liquid,being cooled in said reservoir,-is drawn oif at pleasure for usebyopening the discharge cock, and b reason ofthe reducer admittin"onlyalsma 1 quantity of liquid 'as com are with the vamountdischarged,practically all of the discharge is from ,t e-reservoir and. of{substantially the. same temperatureiasity 0 was in the reserv'oir. l Ig 105 JBy the.ciumtructiondescribed; employing the reduced inlet,.po'olersa of this type have fi'-;nind it su e s, t s, nd t ire additionof this improvement itdraw ofithecooled water at from the reservoir forthe reason that the pressure of the supply would prevent the valvebetween the reservoir and the valve chamber, 6 from dropping. It isnecessary to provide a supply for the cooler of greater capacity thanwould be required if the conditions and pressure always remainedunrforin, but the pressure of the water and its conditions vary greatlyin different localities. Further, when a filter is employed in thesupply pipe, besides the variation in the water, the capacity of thefilter itself changes due to the filtering medium becoming clogged intime, and. it is necessary for this reason to install a filter ofgreater capacity-than would be required under favorable conditionsthatis, where the water was very clear and the filter was cleaned often.

. For tliesereasons, therefore, the supply pipe I ply pipe near thecooler a reduced inlet. l This feature insures at least three-fourths ofi the water drawn from the discharge being obtained from the storagereservoir where it has been cooled. It will be seen further that thedevice is automatic in its action in that the supply-needs no regulationfor the reason that the reduced inlet is of suliicient capacity tosupply sullieient water to the reservoir to keep it well filled althoughthe supply may vary for the various reasons mentioned.

Having thus described my invention, I claim:

In a cooler, a su )ply pipe having a reduced inlet, said reduced inletconsistin of a body having supply and discharge ori ass, a hollowperforated plug screwthreaded in said body between said supply anddischarge orifices, and a closed opening in said body in proximity tosaid plug, substantially as and for the purpose specified.
